Talk:Stein's unbiased risk estimate
From Wikipedia, the free encyclopedia
[edit] Improvements?
I think this article has the following problems:
- Something needs to be said about what is meant by "deterministic estimation" etc.;
- It looks as if some of the results are only approximate (eg. unbiasedness) unless only linear models are condsidered;
- A dimensional analysis of the equation for SURE makes it look wrong;
- It is not said what norm is being used.
